AbstractThe importance of software testing and its impact on software quality can't be underestimated. TEF is the automated Bluetooth protocol test system in Symbian platform. It is purely written by Symbian C++ source code, the system is completely platform dependent. Due to the nature architectural design, test logic and implementation are heavily coupled together. As the system consists of thousands of test cases, it is very challenging to maintain and develop further. This calls for a renewal for current Bluetooth protocol testing systems. TTCN-3 developed at ETSI and standardized by the ITU-T, enables the development of a test environment which supported the various types of testing required and the reuse of test artefacts between these test efforts. This thesis reviews the automated system TEF and implements a new test framework with TTCN-3 to addresses the major drawbacks observed in TEF. The new TTCN-3 framework is prototyped with Service Discovery Protocol (SDP) test suites. In this study, we verified that TTCN-3 offers clear improvements over TEF. It improves the test system productivity and quality nearly two times than TEF. Furthermore, test coverage reached 95% in TTCN-3 than 75% in TEF. We recommend implementing test suites for other protocols and profiles in TTCN-3. Furthermore, new TTCN-3 framework needs to be integrated to ATS test automation server in order to be fully automated.
